15 Claims. (Cl. 154-545) My invention relates to printers blankets.

It has among its objects to provide an improved blanket of the type adapted to eliminate a hump or so-called bolster at the edge of the cylinder slot. A further object of my invention is to provide such an improved blanket having an improved hinge construction at a terminal edge of the cylinder. Other objects are to provide an improved hinge construction utilizing a part of the blanket to form a fabric hinge and also having improved means for protecting this hinge in an improved manner. A still further object of my invention is to provide such an improved construction having an improved hinged flap adapted to extend into the cylinder slot and which is markedly stronger and better adapted to be connected to the pins in the slot or to carry a canvas flap connected to a reel, than the mere fabric flaps heretofore used. Still other objects of my invention are to provide such an improved blanket which is adapted to be inexpensively produced from a standard blanket, and which is further adapted to be embodied in either top, intermediate, or bottom blankets, all in such manner as thereby substantially to extend the field of use of such standard blankets at small expense. A further object is to provide improved combinations of blankets whereby the cylinder is packed in an improved manner while utilizing blankets having hinged flaps. These and other objects and advantages of my improvements will, however, hereinafter more fully appear.

In the accompanying drawing, I have shown for purposes of illustration certain embodiments which my invention may assume in practice.

In the drawing:

Fig. 7 is a view similar to Figure 1, but showing a modified construction;

Fig. 8 is a view similar to Figures 2 and 3 showing a further modified construction, and

Fig. 9 is a like view showing a further modifled construction.

In the illustrative construction shown in Figures 1 to 6, I have shown a cylinder I having a slot 2 of any usual form, and blanketing comprising a top blanket, generally indicated at 3, and an under blanket, generally indicated at 4, carried on the circumference of this cylinder; these blankets being of an improved construction and connected in the cylinder slot in an improved manner, as hereinafter described.

Referring more particularly to the top blanket 3, it will be noted that the same, as herein illustrated, includes a comminuted cork body 5 of well known form having top and bottom fabric faces 6 and l suitably attached thereto. Herein, this blanket comprises two portions A and B, of which the portion A is the body portion of the blanket extending around the cylinder, while the portion B is a so-called flap portion formed of the same material as portion A and adapted to be received in the slot 2 while being connected to the portion A by my improved hinge. Herein, this hinge includes a transverse slot 8 extending through the bottom fabric face of the blanket and the cork body 5 to the fabric 6 on the outer face of the cork, in such manner as toform a canvas hinge portion 9. In a preferred construction, this slot is formed by cutting the same in the under face of a completed blanket, care being taken to cut clear through the cork portion 5 without cutting the canvas portion 9 of the top fabric 6 which in use overlies the slot 8 and forms a canvas hinge connecting the blanket portions A and B. If desired, however, the slot may be more shallow, a portion of the cork also remaining uncut. Here attention is also directed to the fact that the walls ill of the slot 8 are of such form and so spaced as to provide an efiective hinge. Further, the width of this slot 8 herein is such that the flap portion B may be disposed substantially at right angles to the adjacent end of the portion A. -Moreover, when so disposed, it will be noted that the adjacent ends I I and I! of the fabric 6 on the under surfaces of the portions A and B are brought into adjacency in such manner as to provide an inner closed right angle corner I3, as shown in Figure 4, which is inwardly spaced from the fabric hinge portion 9, which is then bent around this closed corner outside the latter. While a completely separate drawsheet may be used if desired in the usual manner outside my improved blanket, it will be noted that herein I have also attached such a drawsheet II to my blanket, by suitably cementing the fabric on the inner face I! of this drawsheet directly to the outer face of the fabric 3 so that both sections A and B'underiies this cemented on drawsheet and the hinge portion I between these portions A and B is thus also reenforced by the additional fabric II of the drawsheet. Here also it will be observed that suitable apertures II are provided in the flap portion B to receive the usual pins I! provided on one wall of the cylinder slot 3.

Cooperating with this top blanket 3 is also my improved inner blanket 4, herein forming the bottom blanket. This blanket l is also of my improved hinged construction and includes like parts A and B. This blanket being a bottom blanket, there is of course no drawsheet attached to the top surface thereof. Further, the transverse slot, while of the same depth as heretofore, is of different form from that previously described, the same being in the form of an inverted V-shaped groove l3. Despite this difference in the slot, it will be observed that as shown in Figure 2, this blanket also provides a closed comer I! when, upon bending the flap B, the adjacent edges 20 and 20a of the under fabric 8 are brought together, the sloping sides of the V-slot then contacting each other and thereby acting effectively to protect the fabric hinge portion 2|. Here also it will be understood that where the flap B of such a blanket is to coopcrate with pins ll, apertures corresponding to the apertures ii are provided in the fiap B.

In the use of my improved construction, the blankets 3 and l have their flaps B attached to the pins II, as illustrated in Figure l. The opposite end of the top blanket 3 is connected in any suitable manner as to a usual reel 22, for example, by a canvas tall 23 suitably connected to that end 24 of the blanket 3 which is thus pulled down into the slot 2. Herein, as usual in bottom blankets, the corresponding extremity of the blanket 4 is not connected to the reel, the connection of the outer blanket 3 to the latter being sufiicient, but extends substantially to the edge of the slot 2.

It will also be understood that where a usual form of separate drawsheet is used, as distinguished from the cemented hinge-reenforcing drawsheet heretofore described, a cork blanket similar to the cork portion of the blanket 3 may then be used with or without a blanket I. Also, where there is a bottom blanket l, the outer blanket may also have its flap B extended down into the slot and connected to the reel by an attached canvas tail, in order to prevent displacement of the under blankets should the relatively light drawsheet break. Although I prefer to use ,the form of hinge shown in Figure 3 on the outer of them under blankets, and the form shown in Figure 6 on the inner one of the same, it will of course be understood that a reverse arrangement may be used, and that if desired both of the under blankets may be of either hinged construction. Further, it will be evident that the shape and dimensions of the slot provided may be varied with different blankets, while still obtaining the advantage of my improved hinge and closed comer.

As a result of my improved construction, it will be observed that any hump or bolster is eliminated by 'the hinge. It is also made possible to utilize a portion of the blanket fabric as the hinge and yet this fabric hinge portion is amply protected by the closed corner, the fabric surfaces on the portions A and B of the blanket abutting to form an eii'ective closed hinge protecting corner. Further, the yielding nature of the cork blanket body is such that the fabric hinge and the transverse slot may conform as necessary in each blanket, while the structure is such that as the canvas hinge portion is drawn down around the outer comer, the inner corner is even more effectually closed. In my improved constructions, it will also be observed that it is made possible to provide a flap extending from the hinge into the cylinder slot which is of the same construction as the body of the blanket, and, therefore, markedly better adapted to be connected to pins, or to have a canvas tall attached thereto than a mere fabric extension from one face of the body of the blanket. Further, at the same time that this advantage and the advantages of my improved hinge are obtained, it will also be observed that it is made possible to produce my improved construction by inexpensive and readily made slotting or grooving of a standard blanket.

In Figure 7, I have illustrated a modified construction wherein a like hinge construction is provided at both ends of the blanket 3. Here, the additional flap portion 0 on the blanket 3 has a canvas flap is suitably attached thereto and connected to the reel 22 as heretofore. As shown, the corresponding extremity of the under or bottom blanket 4 extends to the edge of the slot and is not connected to the reel. As heretofore, however, it will be understood that where a separate drawsheet is used, the outer blanket may also have a flap portion corresponding to C and a canvas tail connected thereto and to the reel, in order to retain the under blankets in'position should the drawsheet break.

'ends of sections A and B and connected by a pivot pin 21 slipped through the round protruding ends of the clips. In this construction, preferably thesections A and B, while resilient, are more firm than those in blankets 3 and l and are preferably formed of a series of laminated fabric portions connected by thin layers of re silient adhesive. Such a blanket is especially adapted to use as a bottom blanket and to cooperate with outer blankets such as shown in Figures 3 and 5, wherein there is sufficient resiliency to permit the protruding metal clip ends to be yieldingly received in the inner faces of the closed comer without distortion of the latter or wear on the hinge portion. In Figure '9, on the other hand, it will be observed that while the cork is entirely removed as in Figure 3, a bridging portion 28 is provided by the uncut under fabric I, in such manner as thereby to produce a double thickness hinge of canvas, as distinguished from the single canvas hinges utilized in the constructions of Figures 3 and 6. Here it will be understood that the blanket of Figure 8 may, if desired, be used with a separate drawsheet or with a drawsheet cemented therein Figures 3 or 5 is definitely to be preferred.

Further, the blanket of Figure 9 may, if desired,

have a drawsheet cemented thereto as shown in Figure 3. Obviously, the width of the slots pro vided and the angles of their walls may be varied in the construction shown in Figure 9, as well as in those previously described.

Attention is particularly directed to the fact that in my improved construction cooperating top and bottom blankets are provided having my improved hinged flaps thereon and disposable in a new relation to one another. Accordingly, my blankets may be used in accordance with standard practice in a two or three blanket packing. Further, it will be observed that whether my improved hinge construction is embodied in a top blanket or a bottom blanket or used with a drawsheet cemented to the top blanket or a separate drawsheet, the thickness of neither the top blanket nor the bottom blanket is appreciably increased b the hinge. Instead, the latter is, in all cases, disposed substantially within the thickness or gauge limits of the particular single upper or lower blanket to which it is applied. Thus, it is made possible to apply my improvements without disturbing established gauge limits or established practice as to two or three blanket combinations.

While I have in this application specifically described certain forms which my invention may assume in practice, it will be understood that these forms of the same are chosen for purposes of illustration and that the invention may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
